Abstract
Hg1201 superconductors have been synthesized from Ba-Cu-O precursors i n a two zone assembly. Critical temperatures of 92 K as prepared and 9 5 K after oxygen annealing resulted. The Hg1201 phase forms at mercury pressures above 6 bar (800 degrees C. The effect of dopants on meltin g and annealing temperatures of the precursor materials has also been studied. After Li doping of up to 20 %, melting peaks shift to lower t emperatures and broaden significantly.
